Answer:
$20
Explanation:
Demand is the number of goods and services consumers are willing to consume at a given price over a given period of time. Supply is the number of goods and services that suppliers are willing to produce at a given price over a given period of time. The equilibrium price is the price at which the quantity supplied is equal to the quantity demanded. At this point, there is neither a shortage nor a surplus of the product. In this case, the point at which the quantity supplied of tickets is equal to the quantity demanded by members is at price $20 where both are at 600 tickets. Hence, this is the equilibrium price.
At any price lower than this, quantity demanded exceeds quantity supplied, causing a shortage. At any price higher than this, quantity supplied exceeds quantity demanded, causing a surplus.
